To all: wlronnit may? ooneemr:

Be it known that? IgtFRAN Ki IoRNs GIBBSgasubject ofHis-Maj esty: theKing: of G reatz Britain. and Ireland; residing at 140 Hurst 5 street;Birmingham, England; manufacturem: haveinvented'lnew anduseful-Improvements in Methods of Producing Metallic'vess els byElectrodeposition, of which: the followlng is a: specification.

This invention consists-- of the herein de suitable non-metallic andnon=porous substance and then removed fromsuch models,

so that the body orwma-in-portion of the vessel is metal without anyglass or potteryware or other non-metallic lining. In'order 2 tofacilitate the productionofrstrongzspouts, handles, stems or basesor thelike integral with said vessels I proceedas follows :The glass orpotteryware or other non-metallic and non-porous modelgis formed; withthe required handle orrspout or legs or: stem or the like in a piecetherewith and these are coated with the metallic paint or otherconducting material so that the met'al'willbe electro-deposited on thesehandles or spout or legs or other projecting parts as well as on thebody of the model, but when the body part of the model has been brokenaway and removed the potteryware or glass or other handles or spout orother projecting parts 40 of the model will remain permanently embeddedin the electro-deposited vessel and at their ends where they have beenbroken away from the model inside the vase or other article the glass orpotteryware or other part can be ground down and then coated with themetallic or other conducting material and the required metalelectrodeposited over these ends of the handles or projections so thatthey will not show on the inside of the vessel. Or if desired metalblanks may be fixed to cover these ends of the handle or parts. Thiswill be clear by an examination of the accompanying drawings of whichFigure 1 is a sectional elevation of the handle and part of apotteryware model for forming a tea cup by electro-depositiong Fig, 2*shows the-same parts as -Fig.

1 with the metal electro deposited thereon'gfl Fig: 3- shows-the"deposit" and: the hande part of themodel embedded therein after the"part of: the model which formed the body partof=the tea cup'hasbeenbroken away. and removed from the deposit; :Fig. 4 shows thefinished: tea: cup with the handle part 50f the model embedded inthedeposit and entireliy inclosed as hereinafter described and Fig; l 5is a seotional elevation-of a metal ?drinking:vessel orcup-*with thestem part of the: model" embeddedi therein:

The glass or glazed potterywaretea: cup

mode-lD is formed with' 'a: handle of simi' Elan material and integraltherewith and the exterior of this handle as'well as the'exte rior ofthe model Dare coatediwiththe metallic paint or: other conductingmaterial sothat-the met'al:w-ill beelectro-deposited on to the-handle-Eas well as on to'the bodyD' as in Fig. 2, wherethe'electro-depositaround the handle is marked 1. After the body part ofthe model D has been cracked and broken away from the bodypart 4 of thedeposit thehandle-E will remain in the deposit and the broken awayends-2,\3' of the ihan'dle-will be rough-as in Fig. 3 but these are asabove: described afterward ground down and if desired' are coated withme tallic paint or other conducting material and then metal 5- isdeposited overthem'inso that now the glass or glazed potteryware handleE will be entirely inclosed inside the handle part of the metallicdeposit which is an integral part of the vessel 4. Spouts, legs, feet,or other projecting parts of the metal vessel can be similarly formed onthe glass or potteryware model and then be left embedded in the depositafter the body of the model has been broken away as will readily beunderstood. Fig. 5 shows in cross section a drinking vessel in the formof a wineglass which has been formed by electro-deposition of metal onto a wine glass model in the manner above described, and

the body of the glass model has been broken away and removed leaving themetal vessel body 6 with the glass stem F and foot G part of the modelin the deposit. The upper end 7 of the former glass stem where it hasbeen broken from the body has to be ground down and may if desired becovered by a metal blank 5 or by electro-depositing metal thereon sothat the top end of the ;ing metallic vessels, which consists inproviding a model comprising a body portion having a projecting portionextending outwardly therefrom, applying a conducting surface to saidmodel, electro-depositing :metal on the exterior of the surface of saidbody portion and of said projecting portion and removing the bodyportion of the model and allowing the projecting portion of the model toremain whereby the projecting portion of the finished article willcomprise the projecting portion of the model and the electro-depositedmetal coating upon the exterior surface thereof.

2. The herein-described process of form- -ing metallic vessels, whichconsists in providing a vitreous model comprising a body portion havinga projecting portion extending outwardly therefrom, applying aconducting surface to said model, electro-depositing metal on theexterior of the surface of said body portion and of said projectingportion and removing the body portion of the model and allowing theprojecting portion of the model to remain whereby the projecting portionof the finished article will comprise the projecting portion of themodel and the electro-deposited metal coating upon the exterior surfacethereof.

3. The herein-described process of forming metallic vessels, whichconsists in providing a model comprising a body portion having aprojecting portion extending outwardlytherefrom, applying a conductingsurface to said model, electro-depositing metal on the exterior surfaceof said body portion and of said projecting portion, removing the bodyportion of the model and allowing the projecting portion of the model toremain and grinding down the end of the projecting portion of the modelfrom which the body portion of the model has been broken away.

l. The herein-described process of forming metallic vessels, whichconsists in providing a model comprising a body portion having aprojecting portion extending outwardly therefrom, applying a conductingsurface to said model, electro-depositing metal on the exterior surfaceof said body portion and of said projecting portion, removing the bodyportion of the model and leaving the projecting portion of the model toremain, grinding down the end of the projecting portion of the modelfrom which the body portion of the model has been broken away, andcovering the ground-down end with electro-deposited metal.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
